When Self-Driving Cars Hit a Dead End: Power Outages Expose a Critical Weakness

TechCrunch reported that Waymo briefly paused its robotaxi service in San Francisco this week after a power outage hit about 7,000 PG&E customers. The one-hour stoppage shows how a simple grid failure can bring advanced autonomous technology to a halt. For a service that prides itself on 24/7 availability, this is a stark reminder that even the smartest vehicles still depend on old-fashioned infrastructure.

The event is significant because it’s not an isolated glitch. Waymo has dealt with power-related disruptions before, including a blackout in December and a Fourth of July incident. San Francisco’s mayor is now pushing for stricter state rules on how self-driving cars handle major incidents. This raises a fundamental question: can autonomous systems ever be truly reliable when the electricity grid is unpredictable?

Why This Matters for the Future of Autonomous Technology

From my perspective, the Waymo pause reveals a blind spot in the industry’s narrative. Companies often talk about sensors, AI, and mapping—but rarely about the basic utilities that keep their fleets running. A robotaxi without power is just an expensive sculpture. The fact that Waymo needed to coordinate with local officials and pause service for an hour suggests its contingency plans are still reactive, not proactive.

This is a classic digital transformation lesson: no matter how smart your software, hardware always has physical dependencies. For any business relying on cloud-based or automated systems, this incident should trigger a hard look at redundancy. A power outage doesn’t just stop cars—it can stop payment systems, inventory management, and customer communications. The real test of a digital transformation isn’t the sunny-day demo; it’s how the system performs when the lights go out.

What This Means for Australian SMBs

Australian small and mid-sized businesses face their own power reliability challenges, from summer storms to aging rural grids. If a $200-billion company like Alphabet can’t keep its fleet running during a blackout, how confident should you be in your own core systems? Many SMBs are adopting cloud-based tools for everything from payroll to CRM, often without backup plans for connectivity or power.

The lesson is clear: digital transformation isn’t just about adopting new technology—it’s about building resilience into how you use it. For an Australian retailer or logistics company, a one-hour outage could mean lost sales, delayed deliveries, or angry customers. The Waymo case shows that even the most advanced systems need old-school fallbacks, like offline modes, battery backups, and manual workarounds.

What You Can Do Now

  • Audit your critical business systems to identify which ones stop working during a power or internet outage.
  • Invest in uninterruptible power supplies (UPS) for your core servers, routers, and point-of-sale terminals.
  • Create a simple offline procedure for key tasks like taking orders, recording payments, or communicating with staff—and train your team on it.
  • Test your backup internet connection, whether it’s a 4G modem or a secondary fixed line, at least once a quarter.
  • Review your cloud service level agreements to see what support you get during regional outages or power events.

At MS&VG, we help Australian businesses build digital strategies that don't fall apart when the grid does. From resilience planning to real-world testing, we focus on making sure your technology works when you need it most—not just when everything is running smoothly.
